+ modify configure-script/ifdef's to allow OLD_TTY feature to be
suppressed if the type of ospeed is configured using the option
--with-ospeed to not be a short. By default, it is a short for
termcap-compatibility (adapted from suggestion by Christian
Weisgerber).
+ correct a typo in _nc_baudrate() (patch by Christian Weisgerber,
cf: 20061230).
+ fix a few -Wlogical-op warnings.
+ updated llib-l* files.
